Gerry, according to RT even the SD cards are not compatible. As of last Thursday evening, RT DOES have the programming software available for the 52A Plus, I have it and it copies and downloads just like the other RT programs.
Now my complaint! Even with the GPS, GPS logger and anything else I can think of that can drain the battery, this radio EATS BATTERIEs!! I've had a 51, 51plus, 52 and now the 52 plus, and none of the other radios go through a battery like the 52A plus! The other radios I can get anywhere between 12-14 hors but the 52A plus I'm lucky to get10 hours on a fully charged battery.
Anyone else experienced this issue? If so, how did you or have you not solved this problem???
